Title: Helical antenna
Inventor: KURAMOTO AKIO
IPC: H01Q21/24
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To easily secure the electrical matching and to improve the voltage standing wave ratio, the efficiency and the gain respectively by providing plural radiation conductors on the cylindrical dielectric outer wall, connecting electrostatically one of both ends of each radiation conductor to the dielectric inner wall in different phases, and also connecting electrostatically the other end of each radiation conductor to a matching conductor. SOLUTION: A matching conductor 3 has the electrostatic capacity equivalent to the thickness of a dielectric cylinder 1 and is connected to the radiation conductors 2a to 2d in terms of high frequency. Thus, it's possible to reduce the feeding impedance of the conductor 2a and to secure the proper matching by controlling the width and position of the conductor 3 and also the high frequency degree of coupling even when only the conductor 2a has a high feeding impedance. Meanwhile, the feeding conductors 4a to 4d are placed close to the conductors 2a to 2d via the thickness of the cylinder 1. Then the conductors 4 are connected to the conductors 2 in terms of high frequency via the electrostatic capacity defined between them.

Title: Controlling method for field of engine driven type generator for welding
Inventor: TAKEDA MASANOBU
IPC: B23K9/073
Filed: 1981-04-22
Abstract: PURPOSE:To provide a constant voltage, constant current and desired power drop-off characteristics with one unit of generator in a self-excited shunt generator by controlling the excitation current of the generator in accordance with the deviation between the load voltage and current of the generator and said deviation with respect to the difference between the load current and a reference voltage. CONSTITUTION:A power stabilization circuit 10 outputs a reference voltage in accordance with the output of a rectifier circuit 3. The secondary winding output of a voltage transformer 7 for detecting the load voltage of a generator 1 generates the rectified output of the generator 1 contg. ripple components at both ends of a resistance R8 via a waveform shaping circuit. The voltage by the load current generated in the resistance R1 for detecting the generator is divided to a DC voltage contg. ripple components. For example, if SW1 is switched to a1, SW2 to off and SW3 to b3, only the reference voltage is supplied to a subtraction amplifier IC2, and is introduced to a comparator IC1. When this is larger, said comparator produces an output, and a field winding Fg is excited in such a way that external characteristics assume constant voltage characteristics. If the SW1-SW3 are switched to a1, on, a3 or b1, off, a3, the desired drop-off characteristics or constant current characteristics are obtained.
